nous kinds of treatment, but all to no purpose. However, on Monday, 

 nth of July last, he came to see me, suffering from severe pain in his 

 right elbow and right ankle. With the help of my bees I gave him eight 

 stings, three upon the elbow and five upon the. ankle. When he came 

 he could not lift his arm, and it was with very great difficulty that he man- 

 aged to walk a distance of two miles to my place, but twenty minutes 

 after being stung, he could work his arm about as freely as if he had 

 never had rheumatism in his life, and he walked away like a two-year-old.

A FRIENDLY BUTTERFLY. On a picnic some miles east of Bangor in 

 1890 this very sociable Vanessa antiopa made my acquaintance, one not 

 soon to be forgotten by me. It was a fresh and bright one, and his aim 

 seemed pleasure alone, he acted so lively and pleased. His continued 

 attentions to me as I carelessly swung my net beside the road at last in- 

 duced me to meet him half way in friendliness. Even after catching him a 

 few times and then freeing him he alighted on the net, on my straw hat, and, 

 finally in contentment, on my left shoulder. With my coat off in the heat 

 it seemed to me my white shirt might be the attraction. Thinking my 

 children would be amused, I walked back to the stream and called them 

 up to wonder in their turn. Next we all went further to our lunch place 

 under a big Pine where were others of the party. There for some time 

 he kept his place, apparently much pleased. As time passed I at last 

 began to test the power of attraction, actually driving him with net far up 

 into the tree when he again tried to come back, but was probably scared 

 by some one else at last. Now, the time was long, the distance walked 

 considerable, and his various manoeuvres were quite multifarious. His 

 actions showed pleasure distinctly. F. A. EDDY, Bangor. Me. 



ON THE MORPHOLOGY AND PHYLOGENY OF INSECTS. Under this title 

 the "Annals and Magazine of Natural History" for December, 1892, con- 

 tains a translation of a portion of a paper by N. Cholodkovsky, on the 

 embryonal development of Phyllodromia (Blatta) gennauica, published 

 in the " Me'moires de 1' Academic Impe'riale des Sciences de St. Peters- 

 bourg" (7), xxxviii, No. 5, 1891. As set forth in this translation, M. Cho- 

 lodkovsky advances "the following main theses: 



1. The head of Insects contains more than four protozonites, probably 

 six, of which one is pre-oral, but the rest are post-oral. 



2. The antennae of Insects belong to the first post-oral segment and are 

 entirely homologous with the remaining ventral extremities. They do 

 not correspond to the antennae of Peripatus, but probably to the chelicerae 

 of spiders, and perhaps to the second pair of antennas of Crustacea. 



3. Since the possibility that a number of segments in the germinal streak 

 of different Arthropods have disappeared is not excluded, a homology of 

 the mouth-parts of the different classes of Arthropods cannot at present 

 be set up.
